Description

Tablet coating machine capable of inserting and discharging tablets in a sealed state {TABLET COATER CAPABLE OF TABLET INSERTING AND DISCHARGING IN SEALED STATE}

The present invention allows tablets to be introduced into the coating pan in a sealed state with the front door closed, and the film-coated tablets to be guided to the tablet outlet by a discharge scraper without contamination due to external exposure or exposure of the worker. This relates to a tablet coating machine capable of inserting and discharging tablets in a sealed state.

As is well known, the tablet coating machine (hereinafter referred to as the coating machine) puts tablets inside the coating pan, then rotates the coating pan at low speed using a drive motor to stir the tablets, and sprays the coating liquid using a spray gun inside the coating pan. The tablet is dried by flowing hot air to coat the surface of the tablet with a film.

Meanwhile, when inserting tablets into the coating machine or discharging the coated tablets to the outside after completing tablet coating, the operator opens the front door formed on the front of the coater and manually inserts the tablets, or opens the front door and discharges the tablets. The coater may be designed as an open type so that the coated tablets can be discharged after the chute is mounted on the coater.

However, there is the inconvenience of having to open and close the front door every time when inserting and discharging tablets. When the front door is opened, the inside of the coating machine and the tablets can be easily contaminated with external foreign substances. In particular, it is necessary to avoid exposure of workers. Complete sealing is essential when coating anticancer drugs, but it is not easy to achieve this with an open coating machine.

Accordingly, a technology that can insert or discharge tablets without contamination due to external exposure or exposure of workers is required.

The tablet coating machine capable of introducing and discharging tablets in a sealed state according to an embodiment of the present invention includes a coating pan 111 for coating tablets, a coater body 110 coupled to the inside so that it can rotate forward and backward, and a front surface of the coater body 110. The front door 120 is formed to open and close with a hinge, and the tablet inlet 121 formed at the top and the tablet outlet 122 for discharging the coated tablets to the outside communicate with the coating pan 111. ) is hinged to the spray gun, which is formed to allow entry and exit through the central hole of the front door 120 and sprays the coating solution into the coating pan 111, and is fixed to the inner peripheral surface of the coating pan 111, and the coating It includes a discharge scraper 140 that mixes tablets when the fan 111 rotates forward and guides the tablets to the tablet outlet 122 when the coating pan 111 rotates reversely, and the front door 120 is closed and sealed. In this state, the tablets are introduced into the coating pan 111 through the tablet inlet 121, and the coated tablets are guided to the tablet outlet 122 by the discharge scraper 140.

Hereinafter, with reference to the drawings, a tablet coating machine capable of inputting and discharging tablets in a sealed state of the above-described configuration will be described in detail as follows.

First, referring to FIGS. 1 and 2, the coating machine body 110 has a coating pan 111 on the inside that accommodates the tablets and coats the tablets with a coating solution sprayed from a spray gun (not shown) so that it can rotate forward and backward. are combined.

For example, a motor that rotates the coating pan 111, a reducer that reduces the rotation of the motor, a first sprocket formed at the rear end of the coating pan 111 to transmit the reduced torque, and a second sprocket coupled to the reducer. , It is composed of a chain that links the first sprocket and the second sprocket, so that the coating pan can be rotated forward and backward.

Next, referring to FIG. 1, the front door 120 is formed to open and close with a hinge through an expansion chamber on the front of the coater main body 110, and has a tablet inlet 121 formed at the top, and discharges the coated tablets to the outside. The tablet discharge ports 122 are formed to communicate with the coating pan 111, respectively.

Due to this structure, it is possible to insert or discharge tablets in a closed state without opening or closing the front door 120.

Next, the spray gun (not shown) is coupled to the front door 120 to be opened and closed by a hinge, and is formed to be able to enter and withdraw through the central hole 131 of the front door 120 to spray the coating liquid into the coating pan 111. Let it spray.

Next, referring to FIG. 2, the discharge scraper 140 is fixedly formed on the inner peripheral surface of the coating pan 111, mixes the tablets when the coating pan 111 rotates forward, and mixes the tablets when the coating pan 111 rotates reversely. is guided to the tablet outlet 122 and discharged to the outside.

That is, with the front door 120 closed, tablets are introduced into the coating pan 111 through the tablet inlet 121, and the coated tablets are guided to the tablet outlet 122 by the discharge scraper 140. Therefore, the tablet inlet 121 and tablet outlet 122 perform this without a separate input chute and discharge chute assembly process, so that the tablets are input and discharged in a closed state of the coating pan 111, so that the coating pan (111) The tablet coating process can be performed cleanly by fundamentally blocking internal contamination, external exposure of the tablet, and contamination due to contact with workers.

Here, as in Figure 1 (b) and Figure 4 (b), the discharge scraper 140 is at a first angle (α) between 30° and 50° with the rotation axis (R) of the coating pan 111. It is twisted and extended, and after coating is completed, as the coating pan 111 rotates in reverse, it is inclined toward the tablet discharge port 122, allowing the tablet to slide out under its own weight.

In other words, an inclination angle of less than 30° reduces discharge efficiency due to the slow sliding of the tablet, an inclination angle of more than 50° can prevent a bottleneck phenomenon due to the fast sliding of the tablet, and the first angle (α) is 40°. It may be desirable to be

Specifically, referring to Figures 3 and 4, the coating pan 111 is formed in a cylindrical shape with an inlet hole that narrows toward the open front end (111a) and the rear end (111b), and the discharge scraper 140 is a first guideway 141 formed at the front end 111a and opened toward the inlet hole, and a second guideway 142 in the shape of a triangular piece formed on the cylindrical surface 111c of the coating pan 111. Consisting of, when the coating pan 111 is reversely rotated, the tablets at the bottom of the cylindrical surface 111c are piled up in the second induction path 142, and are slid into the first induction path 141 to reach the tablet outlet 122. ) can be discharged.

Meanwhile, as shown in FIGS. 4 and 5, on the side of the first guideway 141, a guide 143 is formed at a certain height and is bent to prevent the sliding tablet from leaving and surrounds the outside of the first guideway 141. It is formed so that the tablets can be collected and smoothly guided to the tablet discharge port 122.

In addition, as shown in FIG. 2, a plurality of discharge scrapers 140 may be arranged spaced apart at the same angle based on the rotation axis of the coating pan 111, preferably three discharge scrapers 140 spaced apart from each other at 120°. ), so that optimal discharge efficiency can be achieved without the bottleneck phenomenon of the tablet discharge port 122.

In addition, referring to FIGS. 2 to 5, a buffel 150 is disposed on the cylindrical surface 111c of the coating pan 111 at a second angle with an inclination opposite to the first angle of the discharge scraper 140. A plurality of these are arranged and spaced at the same angle based on the rotation axis (R) of the coating pan 111, so that when the coating pan 111 rotates forward, mixing of the tablets is induced, and when the coating pan 111 rotates counterclockwise, the coating is completed. The tablets may be moved to the discharge scraper (140).

Here, as shown in FIGS. 4 and 5, the baffle 150 is formed in the shape of a triangular piece, but is narrowed toward the front end 111a of the coating pan 111, so as to mix the tablets up and down as well as the cylindrical surface ( It is also possible to induce back-and-forth mixing in 111c) and easily guide the coated tablets to the discharge scraper 140.

Meanwhile, as shown in Figure 4 (b), a number of anti-slip bars 151 of a certain height are arranged in the form of horizontal bars at a certain height on the cylindrical surface 111c to prevent the tablets from slipping on the bottom surface when mixing the tablets. This can make mixing of tablets more smooth.

That is, the anti-slip bar 151 functions as a non-slip ledge, allowing the tablets to be further mixed as they pass over the anti-slip bar 151, thereby improving the coating efficiency and drying efficiency of the tablets.

Therefore, due to the structure of the tablet coating machine that allows tablet input and discharge in a closed state as described above, tablets are input into the coating pan with the front door closed and sealed, without contamination due to external exposure or exposure of the worker. , tablets that have been coated with a film can be guided to the tablet discharge port by a discharge scraper.

The embodiments described in this specification and the configurations shown in the drawings are only one of the most preferred embodiments of the present invention and do not represent the entire technical idea of the present invention, so various equivalents may be substituted for them at the time of filing the present application. It should be understood that variations and variations may exist.
